Hi guys, to enable changes, you need to upload bin files to the router? BIN-NSS.FW.12.0.r1-002-HK.R.tar.bz2, or is it necessary to rebuild the OpenWRT assembly?
I just copied the two new files, and it seems to work with Robi's latest build.

Tell me in which directory to copy the files ?, I have an Xiomi AX3600 router with the latest firmware Openwrt from robimarko.
In the directory /lib/firmware/ I have files qca-nss0-retail.bin qca-nss1-retail.bin, should they be replaced ?
Yes. The name needs to be the same though. Based on the size you can tell which one is which. Both files are needed.
But we don't have a working nss-drv (for the 5.15 kernel), so just copying the nss bins at the right place doesn't lead to working nss acceleration.
That is clear to me 
I am already happy that it wont crash anything, as I believe even without the nss-drv the firmware is loaded non the less.

Nope, without NSS-DRV NSS fw is not used at all, not even loaded

Good to know. So surprises can emerge when you re-add it... 
Well yesterday I tried to OC ax3600.
I added the missing clock steps to ipq8074-ac-cpu.dtsi build it and my joy only lasted 30 seconds.
htop shows the OC cpu steps, it looks like it's working, but wen I ran coremak, the bench show there is no increase in speed.
It doesn't work.
You didnt really think that it would work at 2.2 GHz

First I only tried 1.6 and it looked good, so I went for 2.2 and was thinking Robi code is so good it's even using the correct voltage, but then I thought it couldn't be right and ran the bench.
Use this tool to actually calculate the clock and verify whats actual frequency.
2.2GHz works fine on the Hawkeye models and there is a noticable memory throughput for example

Thanks, I'll try it.
@bitthief repo have a nss-drv that compiles and works + ecm compiles however it crashes the kernel with "Unable to handle kernel paging request at virtual address"

I was trying it, the new SPF 11.5 NSS FW loads like it was said:

nobody cared to update the package to 11.5 am i wrong?
@robimarko if you want i can waste some time on it and push the changes... (ideally on a separate branch?)

I updated to 11.5, can say it loads, but didn't had time for much more.
The new file size can be seen in the logs I posted.
He is talking about the nss-drv and ssdk, not the binary blob of the firmware...
you need ecm ... not just the nss-drv
also note that I noticed a memory leak ... had to increase the drop of caches from every 3h to 30m ... and just 10 clients connecting... this is perhaps because I have the nss-drv loaded
